ABSTRACT
An understanding of forces and torques applied by the feet to the ground during the golf swing is vital for achieving proper mechanics and optimal performance. In this study, ground reaction forces and torques for sixty male golfers of various abilities were recorded. A general description was presented and was consistent with previously published studies. Downswing time was similar for swings with a driver as with a 5-iron, however greater downswing forces and torques at the feet were generated with the driver. Different deceleration mechanics were used for the two clubs. With the driver, the golfer's front foot applied greater lateral force; with the 5-iron the golfer's front foot generated greater outward torque. Differences were also seen between skill levels. The low-handicap golfers achieved maximum torque with the rear foot earlier in the downswing, which can be related to the greater club velocity that was observed for the low-handicap golfer.
